Veri Merkezleri için Türkiye'nin Serbest Soğutma Potansiyeli

Öz

Veri merkezlerinde soğutma amaçlı elektrik tüketimi hızla artmaktadır. Veri merkezlerinde ekipmanlardan salınan ısı odaya boşaltılır ve oda kabul edilebilir sıcaklıklarda tutulmalıdır. Soğuk bölgelerde soğutma için elektrik tüketimini azaltmak için, serbest soğutma teknolojisi geleneksel sistemler yerine daha verimlidir. Serbest soğutma sisteminin kurulumundan önce konumun serbest soğutma potansiyelini bilmek gereklidir. Bu çalışmada, Ankara, Antalya, İzmir, Erzurum, Konya ve Trabzon olmak üzere Türkiye'deki altı il için 15 ° C'den 21 ° C'ye kadar olan besleme havası sıcaklıklarına göre Türkiye'nin serbest soğutma potansiyeli araştırılmıştır. Daha sonra, Ankara'da bir veri merkezinden temin edilen elektrik tüketim ölçümleri kullanılarak her şehir için bir serbest soğutma sistemine sahip bir birgi işlem merkezinin Güç Kullanım Etkinliği (GKE) değeri hesaplanmıştır. Yapılan hesaplamalarda, Erzurum, Ankara ve Konya için GKE değerleri 1.23, 1.37 ve 1.37 olarak hesaplanmış ve serbest soğutma sisteminin uygun olduğu sonucuna varılmıştır.

Free Cooling Potential of Turkey for Datacenters

Abstract

Electricity consumption for cooling in data centers is increasing rapidly. The heat released from equipment’s in datacenters is discharged into the room and room has to be kept at acceptable temperatures. Free cooling technology is more efficient way instead of using conventional systems in cold regions to reduce the electricity consumption for cooling. It is useful to know the free cooling potential of a location before installing the free cooling system. In this study, free cooling potential of six cities (Ankara, Antalya, İzmir, Erzurum, Konya and Trabzon) located in different regions of Turkey is investigated according to supply air temperatures from 15 ˚C to 21 ˚C. Then Power Usage Effectiveness (PUE) value of a datacenter with a free cooling chiller is calculated for each city by using the electricity consumption measurements of cabinets and free cooling system conducted in a datacenter in Ankara, Turkey. Calculations show that free cooling system is convenient for Erzurum, Ankara and Konya with PUE values 1.23, 1.37 and 1.37 and the potential calculated to be almost 100% for eight, six and six months respectively for different supply air temperatures 17 ˚C to 21 ˚C. In addition to cold climates, free cooling system for Antalya in Tsat=19 ˚C is calculated to save 46% energy on annual basis.
